Plants vs. Zombies is an unofficial port of Plants vs. Zombies, made in 2012. It was likely developed by Nice Code. Plants vs. Zombies utilizes the same engine as Angry Birds, and the music was recycled from said game. This port has fewer plants and zombies than the original but is considerably more faithful than the Angry Birds port. Plants vs. Zombies has five levels based on the first five of the official release.
